firebase 연동 후 빌드시 빌드에러가 납니다.

1. android > build.gradle

dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        classpath 'com.google.gms:google-services:4.2.0'
    }

2. android > app > build.gradle

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).

3. android > gradle.properties

org.gradle.jvmargs=-Xmx1536M
android.useAndroidX=true
android.enableJetifier=true

위와같이 설정 후 빌드를 하면

         *********************************************************

WARNING: This version of image_picker will break your Android build if it or its dependencies aren't compatible with AndroidX.

         See https://goo.gl/CP92wY for more information on the problem and how to fix it.

         This warning prints for all Android build failures. The real root cause of the error may be unrelated.

         *********************************************************

FAILURE: Build failed with an exception.

* What went wrong:

The Android Gradle plugin supports only Kotlin Gradle plugin version 1.3.0 and higher.

The following dependencies do not satisfy the required version:

root project 'android' -> org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.71

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org
